The perfect amount of points depends on how often you visit, for how long and what resort you prefer staying at. When we first bought in Oct, we thought we bought the perfect number of points -- 268! That was exactly the number needed for a 1BR at AKV-savanna during Magic season (we never anticipated going during Premiere, and still never plan to

). Soon, we found out that we like to stay longer. Oh, and we like to take guests. Then
DVC did a reallocation and it was now 272 points for the same 7 day stay.

Fortunately we had developer points for our first stay at SSR in 2009; we had 2008 and 2009 points for our second DVC stay with family in 2009. Our third visit was during Adventure season in 2010, so we had enough points for a 2BR for 7 nights and brought friends.
Then I developed a raging case of addonitis in Feb 2011

, just before the resale restrictions, and bought our first add-on contract of 50 points in March 2011. This was a very tough-to-cure case of addonitis and another 55 points came in May 2011. Finally I was cured -- until June 2012, when another bout of addonitis left us with another 105 points. Fortunately, all of these came with a fair number of banked points, so we have had extras to work with for the past two years.
Now, with 478 points at AKV, we can host friends or family in a 2BR for 7-9 days or go alone in a 1BR for 10-12 days! I do worry a little that with DS turning 7 and getting more involved in summer activities, we will eventually have more than we need. But, we can always stay in larger accommodations (can you say GV?!?!) or let friends or family "borrow" some points for a stay. Of course, we could add a long weekend during F&W every fall!
I must admit, I have recently had a nagging ache and low-grade fever and I think another case of addonitis is brewing, although this time for an Epcot resort. My DW is doing her best to help me fight this, but it may be resistant to her therapy!!
